Improvement in bottle-stoppers



UEHTEJJ STATES PATENT OFFICE JOSEPH M. HOYT, OF LYNN, MASSACHUSETTS.

d IMPROVEMENT IN BoTrLE-sTorPERs Specification forming part of Letters `Patent No. 186,476, dated January 23, 1877; application tiled` January 9, 1877. l

To all whom it may concern:

Be it known that l, JOSEPH M. HoYT, of Lynn, in the county of Essex and State of Massachusetts, have invented a new and useful-Improvement in Bottle-Stoppers, of which the following, taken in connection with the accompanying drawings, is a specification:

My invention relates to thatclass of bottlestoppers in which rubber or other elastic may terial is used as a packing, in combination different levels, to receive and form bearings for the bail or yoke, so that, as the packing wears, or the wire of the bail or yoke stretches i or otherwise becomes elongated so that the stopple will not close the bottle perfectly tight, the difficulty may be remedied by turning the metal collar or follower partially around, and placing the bail or yoke in the notch or groove whose bottom is at the next highest i level,

lthereby taking up the slack occasioned by wear or otherwise.

Figure 1 of the drawings is a side elevation of the neckof a bottle, showing my improvement applied in connection with Quillfeldts patent stopple. FigtZ is a central vertical section of the same. Fig. 3 is a plan, Fig. 4 an elevation, and Fig. 5 a vertical section, of the metal collar with my improvement applied thereto.

In the drawings, A is the bottle; B, the rubber stopple, consisting of the stem a and disk b, and provided with a hole transversely through the stem, for the passage of the wire bail or yoke c, bent into the form of a letter U,and provided with a hook at its two ends,

which enter eyes d d, formed in the bent-wire lever c, which, in turn, is pivoted at f f to eyes formed in the Wire g, which is iirmly secured around the neck ofthe bottle, precisely as described in Quillfeldts patent, before cited. C

.is a sleeve-shaped cap-piece, fitted over the l stem a. of the stopple B, and provided with a projecting ilange or collar, h,- to bear upon the outer edge of the ange or disk b of the stopple B, and press it down firmly upon the end of the bottle, when the yoke c is drawn downward, by throwing the lever-frame e into the position shown in the drawings, the horizontal portion of the yoke c resting in a notch or groove across the top of the sleeve cap-piece, as shown and described in IQuillfeldts patent.

The sleeve cap-piece G is made of metal, and, as constructed by me, has formed in its upper surface the radial grooves i, 1, and i?, two or more of which may be used, said grooves being made of varying depths, as clearly indicated by the dotted lines in Fig. 4.

The operation of my improvement is as follows: When the bottle is first filled, the yoke c is placed in the deepest groove t', where it is retained by the tendency of the stem a of the rubber stopple B to contract, and when the stopple is forced into the bottle, by throwing the lever-frame e into the position shown in the drawings, the bottle will be stopped tight, because the operating lever-frame and yoke are adjusted so as to accomplish this result when the yoke is in the groove i.

When, in the course of time, the rubber stopple B becomes worn or permanently compressed into a smaller compass than when new, or the yoke,from any cause, becomes elongated, so that the movement of the leverframe c into the position shown in the drawings will not close the bottle. tight, the sleeve C is partially revolved around the stem a of the rubber stopple, and the yoke cis placed in the groove il, the elasticity of the stem a enabling this to be done with perfect ease.

After a still further use of the stopple, and it is found to be imperfectly tight, Vthe sleeve is again partially revolved and the yoke tic stopple and a U-shaped yoke, for holding placed in groove 2, when it is again as good the stopple in place on the bottle, substanas new. tially as described.

What I claim as new, and desire to secure Executed at Boston, Massachusetts, this by Letters Patent of the United States, is- 4th day of January, 1877.

The metal sleeve or collar C, provided JOSEPH M. HOYT. with two or more notches or grooves cut in Witnesses: its upper face, with their bottoms at different N. C. LOMBARD,

levels, when used in combination with au elas- E. A. HEMMENWAY.
